Dear all,

I use impi and when I submit o job (via LSF) to more than one node I get 
the following message:

    Number of CPUs detected (16) does not match the number reported by
    OpenMP (1).
    Consider setting the launch configuration manually!
    Reading file test184000atoms_verlet.tpr, VERSION 4.6.2 (single
    precision)
    [16:node319] unexpected disconnect completion event from [11:node328]
    Assertion failed in file ../../dapl_conn_rc.c at line 1179: 0
    internal ABORT - process 16

I submit doing

    mpirun -np 32 -machinefile nodelist $EXE -v -deffnm $INPUT

The machinefile looks like this

    node328:16
    node319:16

I'm running the release 4.6.7.
I do not set anything about OpenMP for this job, I'd like to have 32 MPI 
process.

Using one node it works fine.
Any hints here?

                                                              Éric.
